基于政府采购数据的长江中游城市群网络特征与影响机制
Network Structure and Influencing Factors of City-Government-Enterprise Linkages in the Middle Reaches Yangtze River Urban Agglomeration
摘要
Abstract
As economic globalization and informatization continue to advance and regional integration develops,interregional urban relations are being reconfigured by various mobile elements.Based on complex network theory,academics have conducted numerous studies on the network structure of urban agglomerations using relational and flow data,such as economy,trade,human mobility,and enterprise branching.However,there are fewer urban networks based on the perspective of government and enterprise linkage,and an in-depth portrayal of government-enterprise linkage networks helps to understand the urban economic interactions implied by the government-enterprise linkage and promote the development of regional economic integration.The study of government-business networks can help elucidate the economic interactions between cities implied by government and business linkages and promote regional economic integration.The pattern characteristics of city networks of government-enterprise linkages in urban agglomerations are explored using social network analysis based on government procurement data of the city agglomerations in the Middle Yangtze Urban Agglomeration,and the influencing factors are explored from the perspectives of proximity and city attributes through a negative binomial regression model.We found that:the procurement method of the city cluster in the Middle Yangtze Urban Agglomeration is dominated by public tendering,and the blocking effect of geographical distance affects the procurement method;the provincial capital city is the dominant city in the government procurement network of the Middle Yangtze Urban Agglomeration,with Wuhan and Changsha pointing to the obvious most wanted link,and Jiujiang playing a more prominent role as a bridge in the network;the linkage of the Middle Yangtze Urban Agglomeration is dominated by the linkage within the subcities,the linkage across the provinces and regions is weak,and Jiujiang plays the role of"broker."The"broker"role of the plate four and take the role of intermediary to promote the connection and transmission of the relationship in the overall network;the Middle Yangtze Urban Agglomeration government-enterprise linkage network is affected by the proximity and city attributes,the economic proximity,organizational proximity,financial expenditures,and the market environment pre-promotional role.Geographic distance and economic scale play negative roles in city networks.This study enriches the perspective of urban network research and contributes to a deeper understanding of urban economic interactions in the context of governmental and business connections.关键词
